Apelicationlfiled June 19,

This inventionrelates toshoes, the primary r object being to provide 'a shoe all portions-of which except the outer soles, are formed of metal preterably'aluminum.

i .5 inothor object is to provide anall metal shoe having an upper so constructed. as to flex under the action of the 'foot .to which the shoe isapplied. v 1 or A further object is to provide an all metal 10 shoe utilizing a middle sole for'medfof telescopically connected members extending throughout the lengthof thesole and held apart yieldingly by an interposed cushioning spring. V a p i A still-further object is'to providea shoe of this character the outer soles of which can be easilyremoved andnew ones placed in v position readily by the user.

It is a well known fact that shoes formed of leather frequently causerailments of the feet because of the dyesand acids used in the treatment of the leather. lliea thershoes are likewise objectionable because they are not water proof, because. they are excessively heavy when made sufficiently durable for use by laborers and mechanics, and because many of them frequently become wrinkled and unsightly after being usedfor a short time.

It is anobject of thepresent.inventionjto providean all metal shoe which doesnot-haye the objectionablefeatures above enumerated andfiu-rthermore, can be easily prov ded Wltl'l a coating material of any deslred QOlOI'fWlll -hold-its shape indefinitelyg' ca'n be cleaned" readily, and can be made as cheaplyas ordinaryleather shoes. i 4

It is also anobject of the invention to provide a shoe'which acts as an efficient support for the foot and ankle, the resilient cushioning middle sole being extended throughout the width of the foot and being equally efii- 'cient' as acushioning means throughout its "width and length.

With the foregoing and other objects in view which will appear as the description jnfo'ceeds theinvention' resides'in the combination and arrangement of parts and 1n the- "details of construction hereinafter descrlbed I 5 ferredform-"of the invention has been shown.'

The insole2 is made .ins .t-egral with the upper and said upper-is open jacent to the .closed toe n'ortion5, withatrans:

as the-ordinary leather soles project, although w it is to he understood that'the extent to which depend on the style of shoe that is made." Q i The'middle sole also includes a relatively thick'bottom plate 13 having a continuous flange il-whieh extends upwardly into the spacesurroundedby the flan e 11 and is outturned as at 15 so as to provide a tight sliding connection between the partswhereby lower 1 plate 13 will telescope relative to' the upper plate 10. l H V Formed in the toe portion of the plate 13 and extending along the sides of said plate back to the front portion of the arch 16 is a groove 17 adaptedto receive the reduced edge portion 18 ofan. outer sole 19 formed of leather or other suitable material. A retaining strip 20 bears against that portion 18 of the outer sole seated in the grooi e 17 and is held detachably to the plate13 of themiddle sole by screws 21 extendingthrough the strip 20,

through themarginal portion 18, and into the plate-13.";

It will be understood from the foregoing description that-the outer sole 19fwill be held securelybut detaehably to' the middle sole and when it'beeomes worn itcan beremoved a groove 23 extending partly or entirely replacing the strip 20.

readily simply byremoving the screWs'21,

lifting the holding strip 20 from theshoe, and then 1 substituting another outer sole19,

7 Plate 13 is provided, on itsback portion, with a depending heel block 22 whichfcan' be made integral therewith or fastened thereto by any suitable means. 'This heel block has around the outer edge portion of the bottom thereof and said groove is adapted to receive the reduced marginal portion 24 of a heellift 25 formed pre'ferably'of leather. This marginal portion is held to the heel block 22 by V means of a properly shaped holding strip 26 which clampsupon the marginal portion of [skilled artisan.

It' is to be understood the heel lift and is held detaehably to theheel block by screws 27 or the like. Thus it will be seen that by removing the stripv 26 the heel lift can be removed and anothersubstituted therefor without requiring the services o f a o t course that the middlejsole made up ofthe parts 10 and 13 "is properly shaped. For the purpose of providing resiliency there is arranged within the middle sole betweensthe members '10 and 13 an "undulating spring strip 28 which extends throughout the length of the space be tween the members 10 and 13 and also extends "practically throughout the width; thereof.

This spring thus provides a yielding support for the foot throughout the width of the shoe and affords a resiliency which is very-desirableand equal to or superior to that resulting th'e heel lift; PlatelO can be connected to from the use of-all rubber soles. J i w 3; A It is preferred to make of aluminum all parts of thisshoe, except the outer sole and the insole 2 by any suitable means such-as an adhesive, solder, or the like. The entire shoe.

can be finished with a colored coating of paint or enamel and will "maintain a smooth and can be made attractivefinish. Thejeonstruction "of the."

sole is such as to ,rovidea firm support on which the feet will bewell balaneeda The shoe is cool during (warm weather, is Water tight, and provides a comfortable support for the entire foot without interfering with proper flexion. Thespring used can be made of a resilient aluminumf alloy or, if desired,

' of any other suitable resilient material. As

the shoe ispracticallyall metal butof alun11- hum, illWlll be light as well as durable and 1 will beespecia-lly adapted for use by me-, chanics and laborers althouglithe models can be veryattraotive'so 'asto be women any "occasion" 1 'Instead of using leather in ltheifor mation .of the outer sole and the heellii't,these parts of other materials such as rubber, etc. W

It is to be understood of oourselthat in-,

stead of making the'shoelof aluminum any other suitable metals or non-porous materials can be used. p i I What is'claimed is:
